CAMERA ATTACHMENT.

Specification of Letters Patent.

Patented Aug. 10, 1915.

App1ication filed October 19, 1914. Serial No. 867,370.

To all whom it may concern:

Be it known that I, JEssE A. NORTON, a citizen of the United States, and a resident of Joliet, Illinois, have invented a new and useful Camera Attachment Device for Operating a Camera- Shutter Release Automatically; and the objects of my invention are to enable the operator of a camera to be away from the camera when the same is operated by means of my invention of an automatic device which is simple and inexpensive and unlike the costly mechanical clockwork devices used for similar purposes.

In the accompanying drawing which illustrates my inventionFigure 1 is a front elevation of a camera and my device. Fig. 2 is a plan view of the bulb cup. Fig. 3 is a bottom view of the bulb. Fig. 4 is a sectional view of the bulb, the cup and its arm.

The cup 1 has the arm 2 connectedto it. The forked slot 4: is connected to the end of arm 2 and engages the collar 11 of the casing 11.

Fig. 1 shows the bulb 3 inserted in cup 1 and compressed so as to form a hollow in the bulb, which is formed of rubber.

Fig. 4 shows the bulb in the cup in normal form, said cup having the air-vent 6 and said bulb the airvent 7.

The air valve 10 is secured across the air vent 7 and the functions of said valve are to regulate the passage of air out of and into said bulb 3 during the'period of its compression and inflation and to allow rapid expulsion of air by compression and cause very slow inflation by contracting the air vent while the air is returning through the same. The rim 5 on the bulb 3 is to stay or gage the entrance of the bulb into the cup. When the bulb 3 is compressed as shown in Fig. 1 and the arm 2 is adjusted to the collar 11, as shown in same figure 1, the reaction of the bulb will raise or advance the cable 12 in the casing 11 until it comes in contact with the shutter release of the camera and operates the same and thus exposes the plate. This causes no jar to the camera and my device is light and convenientto attach.

Other devices for operating the shutter release are expensive and complicated mechanisms, and are wearing on the camera.

What I claim, is-

1. A device for automatically operating the shutter release of a camera and removably connectible to any standard cable for operating a camera, comprising, a resilient oval-shaped rubber bulb with an air-vent in one of its ends; a valve secured to the outer side of said bulb and across said airvent and punctured; a cup with an air-vent in its bottom and adapted to hold a portion of said bulb so that said air-vents will be nearly contiguous and opposite to each other; an arm secured to the rim of said cup to pendently and removably connect it with the end of the casing of said cable in such a position that the compressed end of said bulb will be adjacent to the projecting end of said cable and the resilient action of the said bulb will move said cable forward in its casing until it operates said shutter release.

2. In a device of the class described, an elastic oval-shaped rubber bulb perforated at one of its ends; an air valve secured to the outer side of said bulb and across said perforation; artificial means for holding the compressed unperforated end of said bulb against the projecting end of a camera cable, so that the resilient action of said bulb will move said cable forward through its casing until it operates the camera shutter release, substantially as described.

3. A device for a camera shutter release, comprising, an elastic rubber bulb provided with an air-vent; a holder for said bulb detachably connected with the end of said cable in such position as to hold a compressed part of said bulb against the end of said cable, so that said cable will be moved in its casing and operate said release.
